the local LAN station address. This string should contain an even number of
hexadecimal digits. If you supply an odd number of digits, a hexadecimal “F”
is added to the end, making an even number of digits. See the considerations
for the ADD SU command (concerning protocol selection) for information on
when to use this attribute. To reset this field to its default value, set the first
byte to ZOS4-VAL-ADDR-RESET-BYTE.
ZX25ACCEPTCHG
specifies whether an incoming call request that contains a request for the
recipient to pay the charge is accepted. ZSPI-VAL-TRUE means that collect
calls are accepted. ZSPI-VAL-FALSE means that collect calls are not accepted.
ZX25CUG
specifies the closed user group ID (CUG ID) that is sent in every call-request
packet. If no CUG ID is specified, X25AM sends the CUG ID of the associated
X25AM line. Acceptable values range from 0 through 9999. To reset this field
to its default value, set the first byte to ZOS4-VAL-CUG-RESET.
ZX25DESTADDR
specifies the network address that is used as the called address in an outgoing
call request packet. The address is a string of decimal digits (0 through 9), up
to a maximum of 15 digits. To reset this field to its default value, set the first
byte to ZOS4-VAL-ADDR-RESET-BYTE.
ZX25NEGOT-L3-WIN, ZX25NEGOT-PKT-SIZE, and ZX25NEGOT-THRUPUT
specify the action to be taken when a call request is received with
unacceptable values for one of these characteristics. If a call request packet
with an unacceptable value for either L3 window, packet size, or throughput
has been received, and that characteristic is defined as negotiable (the
respective parameter has been set to ZSPI-VAL-TRUE), a call accept packet
containing an acceptable value for that characteristic is sent to the network. If
the characteristic is non-negotiable (the respective parameter is set to ZSPI-
VAL-FALSE), the call request is denied.
ZX25PORT
specifies the logical port number used by the subdevice. Acceptable values
range from 0 through 9999.
ZX25PRICALL
enables or disables the capability of making priority calls. If set to ZSPI-VAL-
TRUE, priority call capability is enabled; if set to ZSPI-VAL-FALSE, the
capability is disabled. This attribute is used only for the DATAPAC network;
it must be OFF (ZSPI-VAL-FALSE) if the network is other that DATAPAC.
